Nodal Period of an Earth Satellite

Description:Calculates the nodal period of a satellite using a numerical integration technique. The algorithm first uses the RKF78 method to propagate the first-order perturbed equations of satellite motion forward in time to bracket a "nodal objective function". Once a bracket is found, the algorithm then uses Brent's root-finding method to find the time at which the objective function is zero to within a user-defined tolerance. While looking for the root the software also uses the RKF78 method to propagate the satellite's orbit subject to the main oblateness gravity perturbation of the Earth.
